A Comparison Between Multi-Spectral and Hyperspectral Platforms for Early Detection of Leafy Spurge in Southeastern Idaho
ثبت نشده
چکیده
Knowledge of the distribution of invasive plants and early detection of these species is critical for both short and long-term management of ecological systems. This study compared the quality of products derived from various multi-spectral (Landsat 7, SPOT, and Quickbird) and hyperspectral (HyMap) imaging platforms for early detection of the invasive plant leafy spurge. For each platform, the study compared: 1) detection accuracy, 2) ease of processing, and 3) cost effectiveness. We found that both SPOT multispectral and HyMap hyperspectral data were able to yield reliable detection accuracies (>70%) with reasonable processing demands. SPOT imagery yielded results which were most cost-effective; however, HyMap data allowed researchers to reliably detect smaller infestations.

Leafy Spurge (Euphorbia esula) Classification Performance Using Hyperspectral and Multispectral Sensors
Two demonstration sites in southeast Idaho were used to extend the scope of remote sensing of leafy spurge research toward investigating coarser scale detection limits. Hyperspectral images were obtained to produce baseline leafy spurge maps, from which spatially and/or spectrally degraded images were subsequently derived for comparative purposes with Landsat 5 Thematic Mapper (TM). The baselin...
متن کاملAccuracy assessment for detection of leafy spurge with hyperspectral imagery
When flowering, leafy spurge (Euphorbia esula L.) has conspicuous yellow-green bracts that are spectrally distinct from other vegetation and may be distinguished with hyperspectral remote sensing. In July 1999, Airborne Visible Infrared Imaging Spectrometer (AVIRIS) data were acquired in northeastern Wyoming, near Devils Tower National Monument. Using the reflectance spectrum of flowering leafy...
متن کاملEstimation of leafy spurge cover from hyperspectral imagery using mixture tuned matched filtering
Leafy spurge, Euphorbia esula L. is an adventive, perennial weed that infests approximately 1.2 million ha of land in North America. It often forms dense stands that displace native vegetation and useful forage plants on rangelands and in riparian habitats. Leafy spurge is a good candidate for detection via remote sensing because the distinctive yellow-green color of its bracts is spectrally un...
متن کاملDetection of Flowering Leafy Spurge With Satellite Multispectral Imagery
The distribution and abundance of flowering leafy spurge (Euphorbia esula L.) can be determined with hyperspectral remote sensing, but the availability of hyperspectral sensors is limited. Hence, the Landsat 7 Enhanced Thematic Mapper Plus (ETMþ) and System Pour d’Observation de la Terre (SPOT) 4 imagery were acquired to test the ability of these sensors to detect leafy spurge. The green:red ba...
متن کاملSheep preference for leafy spurge from Idaho and North Dakota
Three trials were conducted to determine if low ingestion of some leafy spurge (Euphorbia esula L.) by sheep is primarily due to differences in sheep or in leafy spurge. In the first trial, pastures in Idaho and North Dakota were grazed by sheep originating from both states. Generally, sheep from both states grazed the leafy spurge growing in the Idaho pastures reluctantly but grazed the leafy ...
